SPEOI'FIGATION.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, RICHARD ALLEN, of Jersey City, in the county ofHudson, and State of New Jersey, have invented a new and improvedCarrier or Clutch for Lathes; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same.

The present invention relates to a carrier or clutch for lathes, of that-class of clutches which areemployed for the turning of bolts moreparticularly; and the invention consists in so constructing the saidclutch `or carrier that bolts of various sizes, whether with or withoutheads, may be properly held and secured within 'the same, as will beobvious from the following detail description, reference being had tothe accompanying plate of draw. ings, in which s p p i Figure 1 is aface view ofthe same; an

' Figure 2, a transverse vertical section taken in the plane of thelinea: x, fig. 1.

Similariletters of reference indicate like parts.

A., in the drawings, represents my new and 'improved clutch or carrierfor lathes. This clutch, A, :consists of a. cross-ban'B, having ascrewbolt, C, which, when the clutch is to be secured to the lathe, ispassed through l p the face-plate of the same, and there fastenedby ascrew-nut, D, with washers or rings, E, btweenl such nut and the saidplate, and also the latter and cross-bar, B, according to the distanceat which it is desired "to have the clutch stand from the saidhead-plate, as plainly shown in iig. 2 of` 'the drawings. To thecross-bar B, the` upper ends of similar arms F are hung, one upon ca chside of the bolt C, `so as to. be moved 4in and ont upon the saidcross-bar, according to the distance at which it is desired to set oi'Vplace them apart; these arms, F,

being secured in whatever position they may bel placed, by thescrewinguprofzthe` nut D, herei'nbefore `referred A, to, which acts upon them,by and through the cross-arm or bar, G, loosely hung upon thescrew-bolt, and `interi posed between the arms, E, and the outer washeror ring of the series of "washers upon-the `oui-:side of the faceplate.In and between the arms, F, of the carrier or clutch, one end vci" the'boltwhich is to be turned in `the lathe, is-secured; this bolt, ifprovided with no head, being fastened in the'hollownut by a`set-s'crewJ,and this' nut secured in and between the arms, E, as is plainly shown iniig. 2 of the drawings; but if the bolt is headed,

'the nut, I, is dispensed with; Vthe arms, F, by being arranged or hungupon the cross-bar, B, as herein above explained, enabling them tobeadjusted and set to correspond with the size of anyfbolt or itshead,`whether i i large or small, within the limits of the length of thebar B, as isv obvious, without any further explanation;

I claim as new, an'd desire to secure by Letters Patent p Y A Thecarrier clutch constructed and operating substantially as described. Theabove specification of my invention signed by me this 18th day ofSeptember, 1866. i v
